PRODUCT DESCRIPTION
Product Features
Functional / Interface
Maxtor DiamondMax™ VL 17 hard drives contain all necessary mechanical and electronic parts to interpret
control signals and commands from an AT-compatible host computer. See Section 3 Product Specifications, for
complete drive specifications.
Zone Density Recording
The disk capacity is increased with bit density management – common with Zone Density Recording. Each
disk surface is divided into 16 circumferential zones. All tracks within a given zone contain a constant
number of data sectors. The number of data sectors per track varies in different zones; the outermost zone
contains the largest number of data sectors and the innermost contains the fewest.
Read/Write Multiple Mode
This mode is implemented per ANSI ATA/ATAPI-5 specification. Read/Write Multiple allows the host to
transfer a set number of sectors without an interrupt request between them, reducing transfer process
overhead and improving host performance.
UltraDMA - Mode 4
Maxtor DiamondMax VL 17 hard drives fully comply with the new ANSI Ultra DMA protocol, which
greatly improves overall AT interface performance by significantly improving burst and sustained data
throughput.
Multi-word DMA (EISA Type B) - Mode 2
Supports multi-word Direct Memory Access (DMA) EISA Type B mode transfers.
Sector Address Translation
All DiamondMax VL 17 drives feature a universal translate mode. In an AT/EISA-class system, the drive may
be configured to any specified combination of cylinders, heads and sectors (within the range of the drive's
formatted capacity). DiamondMax VL 17 drives power-up in a translate mode:
(*) The fields LZone (Landing Zone) and WPcom (Write Pre-comp) are not used by the Maxtor hard drive
and the values may be either 0 or the values set by the BIOS. All capacities listed in the above table are based
on 10
